Original Title: British Media: Scientists have found the largest known black hole, nearly 9 billion light years & # 39; away from World

British media said the observer of gravitational waves interferometru discovered four laser & # 39; & # 39 pairs; black holes, including the largest black hole to date.

According to the website & # 39; & # 39 weekly; "New Scientist" reported on 3 British & # 39; December, the station & # 39; gravitational wave observation laser interferometru USA (LIGO) ago monitor gravitational waves. LIGO announced the discovery of & # 39; four & # 39; shackles of & # 39; space created during the rotation and the impact of & # 39; pair & # 39; black holes around each other.

The team of LIGO announced earlier that in the past three years found gravitational waves & # 39; collisions between a pair of neutron stars, four & # 39; Pairs & # 39; double black holes, and a pair of black holes do not know well. new document published last week confirmed that LIGO discovered four & # 39; other activities. The paper also confirms the previously found uncertainty is indeed a sign of gravitational waves. This means that the LIGO & # 39; now mmonitorja 11 different activities: a pair of black holes 10 and one pair of & # 39; neutron stars.

The four & # 39; discovered new activities were examined by previous comments & # 39; LIGO. The members of the team & # 39; LIGO Nelson Christensen said at Carleton College & # 39; Minnesota researchers observed signs of & # 39; these activities in 2017, but not "obvious" as the activities already documented, and thus should be more careful. Analysis.

Among the four & # 39; & # 39 associations; black holes announced this time, occurred between black hole b & # 39; equivalent to 34 suns mass black hole and b & # 39; equivalent to 50 solar mass. This is the largest black hole ever observed LIGO. He also black weight most & # 39; away, almost 9 billion light years & # 39; away from Earth.

Christensen said that the size of the black hole is quite strange, because the collapse of & # 39; unlikely star forming such a big black hole. He said: "This is the extent of the black hole size expect to evolve over the planet's evolution, so maybe this big black hole is the result of a combination of & # 39; black holes other small. Maybe a black hole after another. "

LIGO will carry out the next phase of monitoring in 2019, and the large amount of & # 39; resulting data can & # 39; lead to more results. Christensen said: "We can take us to monitor activity 50 in the next round, and maybe even more."

F & # 39; October & # 39; this year, the newspaper reported that there was fear & # 39; the observations & # 39; LIGO may not be able to prove really detect gravitational waves, because the techniques used to analyze the detector noise can be confused. This new document will help resolve this controversy. (Compile / Hu Xue)
